Abstract
  • A process and interoperation technique for using
    three modeling tools (ORA, CASEAR III, and
    Pythia) has been demonstrated using the East
    Africa Embassy Bombing (1998) as an example
  • Outline
  • Approach
  • Models
  • Results

Approach
  • With respect to the suite of models available
    from CASOS, CSC, and SAL the question of how data
    or information can be passed between the models
    is unknown or un-proven.
  • A Limited Discovery Experiment was used to
    explore the potential interoperation between
    modeling techniques to determine if
  • interoperation is possible,
  • various interoperation types can be applied
  • use of such interoperation would improve the
    overall analysis over that provided by the models
    independently.
  • A case study approach was taken using a corpus of
    data about the al Qaeda Bombings of the Embassy
    in Kenya.

4
Approach
  • A single data source, the Anatomy of a Terrorist
    Attack, was used as the input for the
    Demonstration

Controls ?
  • The information in the document was fed into the
    CASOS tool via Automap and edited by the analysts
    who used read the data set

Analyst
Social Network Analysis with Meta Matrix
Data Set About Situation, e.g. East Africa
Embassy Bombing
ORA
Al Qaeda cell organization structure
(Interconnections, minos and maxos
  • Outputs from ORA were used to create CAESAR III
    and Pythia models

Probability profiles for COA analysis
  • Analytical products were produced from the three
    tools

5
Types of Interoperation
  • The basic proposition Understanding of an
    adversary and analysis of Effects based Courses
    of Action can be improved by using these multiple
    models by exchanging information or data between
    them.
  • Three types of interoperation have been
    postulated
  • Human to human (Swivel Chair) (Human gains
    insights from model 1 that helps with the human
    set up or analysis of model 2)
  • Data to Data (files can be exported from one
    model that can be read automatically by another
    model under the direction of the analyst)
  • Automated Model to Model (Model can be connected
    over a network and automatically exchange data as
    they are run)

6
Experiment (Interoperation) Process Example
  • 1. Analyst sets up Automap and Runs ORA
    generating Meta Matrix and XML File for CAESAR 3
    and Pythia
  • 2a. CAESAR III analyst uses ORA file plus
    knowledge from Data Set to generate adversary
    organization models (lattice plus CP net).
    Identifies potential communications links for ISR
  • 2b. The analyst loads ORA file into Pythia and
    refines the model using ORA Meta Matrix in Pythia
  • 3. Analyst uses TIN to produce probability
    profiles, comparing COAs for selection.
  • 4. COA is selected, planned, and executed
    including ISR Tasking
  • 5. Indicator data from ISR used to update Data
    Set and Pythia for on-going Assessment

5 Indicator data

1. Meta Matrix Attributes

2b. File (Agents/ Roles/Task/ Location)
2a. File (Agents/ Roles/Task))
4. Plan Selection and Execution

Step 1 ORA SN (agent to agent view) for East
Africa Embassy Bombing
Case 1
Case 1
  • Opened new Pythia and re-ran the model Case 1
    with low marginals, Now we get the expected
    results

The Kenya Team
The following command structure was inferred from
reports (text) and ORA meta matrix
11
The Kenya Team
  • The same representation in CAESAR III

12
All Structures
  • Lattice Algorithm reveals all possible
    organizational structures (28) of the Al Qaeda
    Kenya cell

Minimum Interactions Between Cell Members

Output to the environment Bombing

Adversary Model of Plan(Based On SNA of Kenya
Attack)
Model was created using Human to Human
interoperation
  • Derived from events and their timing as described
    in Anatomy
  • The actors and their roles from the SNA and
    CAESAR 3 map to the events
  • h and g values assigned based on understanding of
    TIN

15
Adversary Model of Plan w/Blue Interventions
  • Hypothetical Blue actions (as might be perceived
    by the adversary) added

16
Model Created From ORA Analysis
17
Demonstrate Potential
  • The tools and the workflow indicate that
    interoperation can provide a synergist set of
    useful results

18
Problem Definition
  • Given
  • Multiple Knowledge Representations
  • Multiple Reasoning/Computational Approaches
  • Modeling/Analysis Objective
  • A set of questions to be answered by the analyses
    performed on the computational models
  • Solution
  • Identification of Model(s) and/or Combinations of
    Models that offer insight into the solution space
  • Workflow

19
Problem Definition
  • Nexus Between Models
  • What query can be generated in one model that can
    be answered by the other?
  • What are the overlaps among the models?
  • How do we determine if the output of one is
    supported by the output of the other?
  • How do we identify gaps, inconsistencies, or
    incompleteness (need for more information)?
  • Workflow
  • Given an analysis objective, what is the workflow
    (i.e., combination, interactions, and sequence
    of/between models) that exploits the
    multi-modeling nexus in addressing the objective?

Types of Results Achieved
  • Better Model Construction by
  • Providing design parameters for the construction
  • e.g., Social Network to Organization structure.
  • Providing the structure (partially and/or
    completely)
  • e.g., Social Network to Timed Influence Net.
  • Model Validation
  • Results from two models support each other
  • Multi-agent model and Social Network simulation
    models.
  • Enhancements to analysis capabilities of a model
    by employing functionality from another
  • e.g., Temporal analysis of Timed Influence Net
    modes.
  • Construction of new models by embedding multiple
    models in a single framework
  • e.g., Organization and Communication models.

23
Conclusion
  • Three way interoperation between models has been
    demonstrated
  • One tool and its model can assist in the creation
    of a different model in another tool
  • Used a combination of human swivel chair and
    data-to-data interoperation
  • Process workflows are being developed.
  • More effort needed to refine workflows and
    interoperation techniques
  • Need to extend the approach to more models
